Dioecy - Open Access .click

Molecular Ecology, 2017
Abstract Dioecy, the coexistence of separate male and female individuals in a population, is a rare but phylogenetically widespread sexual system in flowering plants. While research has concentrated on why and how dioecy evolves from hermaphroditism, the question of why dioecy is rare, despite repeated transitions to it, has received ...

Androdioecy and the evolution of dioecy

Biological Journal of the Linnean Society, 1984
The likelihood that dioecy could evolve via androdioecy is examined. It is concluded that female-sterility mutations are unlikely to be able to invade populations of self-compatible hermaphrodite species, even if the resources that an hermaphrodite devotes to seed production can be diverted to yield increased survival and also to increase male ...

Evolution of Dioecy in Flowering Plants

Annual Review of Ecology, Evolution, and Systematics, 1980
Dioecy, characterized by the presence of distinct male and female plants, is widespread in angiosperms, being known in 37 out of Engler & Prantl's 51 orders (132). Yet botanists have paid little attention to dioecy, particu larly to selective forces underlying its evolution. Several factors have con tributed to this neglect.

Origins of Dioecy in the Hawaiian Flora

Ecology, 1995
Because of its presumed high levels of dioecy (separate male and female plants), study of the native Hawaiian angiosperm flora has been important in development of many hypotheses about conditions favoring the evolution of dioecy. The importance of ecological correlates with dioecy has proven difficult to assess, however, because of lack of data on the
